Pt. 60, App. A 

e. The preliminary data should be the man-

ufacturer’s best representation of the air-
plane, with assurance that the final data will 
not significantly deviate from the prelimi-
nary estimates. Data derived from these pre-
dictive or preliminary techniques should be 
validated against available sources includ-
ing, at least, the following: 

(1) Manufacturer’s engineering report. The 

report should explain the predictive method 
used and illustrate past success of the meth-
od on similar projects. For example, the 
manufacturer could show the application of 
the method to an earlier airplane model or 
predict the characteristics of an earlier 
model and compare the results to final data 
for that model. 

(2) Early flight test results. This data is 

often derived from airplane certification 
tests, and should be used to maximum ad-
vantage for early flight simulator valida-
tion. Certain critical tests that would nor-
mally be done early in the airplane certifi-
cation program should be included to vali-
date essential pilot training and certifi-
cation maneuvers. These include cases where 
a pilot is expected to cope with an airplane 
failure mode or an engine failure. Flight test 
data that will be available early in the flight 
test program will depend on the airplane 
manufacturer’s flight test program design 
and may not be the same in each case. The 
flight test program of the airplane manufac-
turer should include provisions for genera-
tion of very early flight test results for 
flight simulator validation. 

f. The use of preliminary data is not indefi-

nite. The airplane manufacturer’s final data 
should be available within 12 months after 
the airplane’s first entry into service or as 
agreed by the NSPM, the simulator sponsor, 
and the airplane manufacturer. When apply-
ing for interim qualification using prelimi-
nary data, the simulator sponsor and the 
NSPM should agree on the update program. 
This includes specifying that the final data 
update will be installed in the flight simu-
lator within a period of 12 months following 
the final data release, unless special condi-
tions exist and a different schedule is accept-
able. The flight simulator performance and 
handling validation would then be based on 
data derived from flight tests or from other 
approved sources. Initial airplane systems 
data should be updated after engineering 
tests. Final airplane systems data should 
also be used for flight simulator program-
ming and validation. 

g. Flight simulator avionics should stay 

essentially in step with airplane avionics 
(hardware and software) updates. The per-
mitted time lapse between airplane and 
flight simulator updates should be minimal. 
It may depend on the magnitude of the up-
date and whether the QTG and pilot training 
and certification are affected. Differences in 
airplane and flight simulator avionics 

versions and the resulting effects on flight 
simulator qualification should be agreed be-
tween the simulator sponsor and the NSPM. 
Consultation with the flight simulator man-
ufacturer is desirable throughout the quali-
fication process. 

h. The following describes an example of 

the design data and sources that might be 
used in the development of an interim quali-
fication plan. 

(1) The plan should consist of the develop-

ment of a QTG based upon a mix of flight 
test and engineering simulation data. For 
data collected from specific airplane flight 
tests or other flights, the required design 
model or data changes necessary to support 
an acceptable Proof of Match (POM) should 
be generated by the airplane manufacturer. 

(2) For proper validation of the two sets of 

data, the airplane manufacturer should com-
pare their simulation model responses 
against the flight test data, when driven by 
the same control inputs and subjected to the 
same atmospheric conditions as recorded in 
the flight test. The model responses should 
result from a simulation where the following 
systems are run in an integrated fashion and 
are consistent with the design data released 
to the flight simulator manufacturer: 

(a) Propulsion; 
(b) Aerodynamics; 
(c) Mass properties; 
(d) Flight controls; 
(e) Stability augmentation; and 
(f) Brakes/landing gear. 
i. A qualified test pilot should be used to 

assess handling qualities and performance 
evaluations for the qualification of flight 
simulators of new airplane types.

a. When a fully validated simulation (i.e., 

validated with flight test results) is modified 
due to changes to the simulated airplane 
configuration, the airplane manufacturer or 
other acceptable data supplier must coordi-
nate with the NSPM if they propose to sup-
ply validation data from an ‘‘audited’’ engi-
neering simulator/simulation to selectively 
supplement flight test data. The NSPM must 
be provided an opportunity to audit the engi-
neering simulation or the engineering simu-
lator used to generate the validation data. 
Validation data from an audited engineering 
simulation may be used for changes that are 
incremental in nature. Manufacturers or 
other data suppliers must be able to dem-
onstrate that the predicted changes in air-
craft performance are based on acceptable 
aeronautical principles with proven success
